This tutorial shows how you can set up an Ubuntu Studio 9.10 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge. I want to say first that this is not the…

This will show you how to set up a Samba Domain Controller with a local LDAP backend, using CentOS 5.x (tested on 5.3, still successfully running on 5.4). Includes a web-interface for managing LDAP users/groups/etc. Disable selinux: It will only cause problems, I’m not going to mess with SELinux in this guide other than disabling it. Install some tools rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm yum update yum install openldap-servers nss_ldap samba httpd openssl mod_ssl mysql mysql-server php php-xml php-ldap php-mysql php-pdo php-cli…

Traditionally, when a hardware or software fault occurred on a Solaris system, a message would usually be logged to the appropriate device specified in /etc/syslog.conf, and the rest of the diagnosis and repair was left to the administrator. Predictive Self-Healing technology is introduced in the Solaris 10 OS, which is available for preview through the Software Express for Solaris program. Predictive Self-Healing is a newly designed cohesive architecture and methodology for automatically diagnosing, reporting, and handling software and hardware fault…

With the escalating costs of managing vast networks of servers and software components, attention is shifting towards developing new ways to reduce IT infrastructure costs and better manage systems. While server consolidation and virtualization techniques help improve data center management, better ways also exist to provision applications and enhance security and serviceability. For these resource management techniques to be effective, we must be able to manage applications independently, control resource utilization according to business needs, quickly isolate faults, and ensure…

This document explains the process of migrating Solaris non-global zones from an old LUN to a new LUN. The target audience is system administrators for the Solaris Operating System and storage administrators. This article covers the following topics: Overview Migration Theory Prerequisites Migration Procedure References Overview Migration is the process of moving a zone from a disk to another. The need to move a zone might arise for any of the following reasons: More disk space needs to be provided…

Abstract: This article offers a process to help you support your application within a zone (using the Solaris Zones feature of the Solaris 10 OS). The process includes software installation and configuration as well as zone limitations with workarounds. Also discussed are best practices for application vendors.

I tried out cloning on a Solaris Zone today and it was a breeze, so much easier (and far, far quicker) than creating another zone from scratch and re-installing all the same users, packages, port lock-downs etc. Here are my notes from the exercise: Existing System Setup SunFire T1000 with a single sparse root zone (zone1) installed in /export/zones/zone1. The objective is to create a clone of zone1 called zone2 but using a different IP address and physical network port.…

Understanding processor utilization is important for performance analysis and capacity planning. With the launch of UltraSPARC T2/T2+ based servers I would like to revisit the topic of core utilization. As we have seen earlier, for a Chip Multi Threaded (CMT) processor, like UltraSPARC T1, CPU utilization reported by conventional tools like mpstat/vmstat and core utilization reported using hardware performance counters in the processor are different metrics and both are equally important in performance analysis and tuning. Before discussing the details…

ne of the frequently asked questions regarding ZFS. Is it possible to resize a RAIDZ, RAIDZ2 or MIRRORED ZPOOL? The answer is a littlebit complicated… If you want to change the ‘geometry’ of the ZPOOL (for example: change from a mirrored pool to a raidz, or simply add a disk to a raidz, or change from raidz to raidz2) then the answer is no. But it is possible to change the disks of a pool with bigger ones and use…

With the built in RAID controller when the machine is booting up hit the Ctrl+C to start the LSI Logic Configuration Utiltiy. This link explains the different screens and how to configure the striping and mirroring. http://docs.sun.com/source/819-1157-16/app-biosraid.html#pgfId-1003503 It was very simple to setup. Dave Martini Below is my original question I have a new X4200 with 4 internal drives. I haven’t worked with this hardware before but it appears there is an internal RAID controller that can be used to…
